"I'm very proud of my career and really enjoyed playing my final year on Long Island," Dunham said in a release. "I'm very appreciative of (Isles coach) Ted (Nolan) giving me this opportunity to be part of his coaching staff and work with all of the goaltenders in our system. I'm really looking forward to beginning my coaching career."

Last summer former backup Garth Snow went from backup goalie to GM. He then signed Dunham to be Rick DiPietro's backup.

The 35-year-old Dunham appeared in 19 games, going 4-10-3 with a 3.74 goals-against average and .889 save percentage.

"Mike had an outstanding NHL career and was very well-regarded for his work ethic and his leadership," said Nolan. "I'm very happy to have all of his experience on our coaching staff."

Dunham will be at the Islanders training camp when it begins Friday in Moncton, N.B. During his career, he had 141-178-44 record, 2.74 goals-against average and .908 save percentage. He also played for the U.S. at three Olympic Games.
